“…On the other hand, various types of ion-selective electrodes (ISEs) for direct potentiometry, which permits the determination of ion activities in solution with a high degree of selectivity, have been developed in recent years. Work in this area has been summarized by Fricke (6), Pungor and Buzas (7), Freiser (8), Vesely et al (9), and Moody and Thomas (10).…”

“…Although the inorganic ion-exchangers have been potentially applied for the removal of toxic metal ions like Pb 2+ , Cd 2+ , Hg 2+ , and As + , making ion selective membrane electrode, separation of radionuclide, electrodialysis, etc., but they suffer certain limitations like poor mechanical strength and nonreproducibility . The uses of organic resins are limited by their poor thermal and chemical stability.…”

A new and novel nanocomposite cation exchanger polyaniline-Sn(IV)iodophosphate (PANI-SnIP) has been synthesized using a sol−gel method by the incorporation of precipitates of Sn(IV)iodophosphate into the matrices of polyaniline. The ion exchange capacity of the composite synthesized at pH 1.0 was found to be 1.2 mequiv g −1 for Na + ion. The characterization of the material using simultaneous thermogravimetry−differential thermal analysis (TGA-DTA), Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) reveals the composite nature of the material with uniform surface morphology and formation of particles of size ranging from 20−25 nm. Study of the various physicochemical properties indicates granulometric nature, fairly good thermal and chemical stability, uniform elution, and bifunctional behavior of the exchanger. The selectivity of the composite for Hg 2+ , Pb 2+ , and Ce 4+ in different solvent media along with their reproducible quantitative separation from binary mixture as well as real samples makes it a potential environmental wastewater detoxicant. The limit of detection (LOD) and limit of quantification (LOQ) for Hg 2+ were found to be 0.53 and 1.9 μg L −1 , respectively. The photocatalytic activity of the nanocomposite has been demonstrated by the photo degradation of Methylene Blue (MB) under solar irradiation.

The articles describing new ion-selective electrodes published during the years 2000/2001 in eight leading analytical chemistry journals have been surveyed. Compliance with the IUPAC recommendations of the procedures used for characterizing the selectivity of the new electrodes has been checked. It was found that the information accompanying the selectivity data obtained according to the procedures recommended by IUPAC or their variations was frequently insufficient for interpreting of the electrode behavior and comparing with other sets of data, thus reducing the significance of the values provided. Some criteria for improving the communication between researchers in the field are suggested.
